To reach the mine from Platteville, starting at the intersection of HWY 85 and Justin Ave (HWY 66) go west on Justin Ave 2.5 miles to Weld County Road 21, then north 1.37 miles to the entrance. The coordinates of the entrance are 40°13'25.1536", -104°52'02.8563". Please refer to EXHIBITB-VICINITY MAP for the property configuration and the relationships to sur- rounding geological features. The area to be mined lies between County Road 21 and the South Platte River, straddling 32.5 Road and lies within the Town of Platteville, Colorado. GENERAL INFORMATION The primary commodities to be mined are sand, gravel, top- soil, overburden, and borrow materials. No incidental commodi- ties will be produced at this mine. Throughout this application we will refer to the two areas, (a) the south area containing Phases 1 & 4 and (b) the north area containing Phases 2 & 3. The roadways (transportation corridors) are left out of the permit since L.G. Everist, Inc. does not own them. Permit/affected lands and mining lines and setbacks vary throughout the site, depending on ROWs and proximity to the South Platte River. Along the river the permit/affected lands line is 100 feet from the western bank of the river. Along the river in Phase 2 (north of CR 32.5), the mining line will be 250 feet from the upper river bank. Along the river in Phase 1 (south of CR 32.5), the mining line will be along the west side of the old railroad grade, which is greater than 345 feet from the river bank. Along the County and Local Roads, the permit lines use the ROW lines associated with the roads. Platteville requires 80 feet ROW for CR 32.5, and Weld County requires 40 feet, east of the section line, for the ROW along CR 21. The slurry walls will be constructed 15 feet from the Per- mit/Affected lines or utility ROW lines, whichever is greater. The mining setback will be 25 feet inside the slurry walls. Mining in all Phases will be done after the slurry walls are completed around them so they can be dewatered and mined dry. Dewatering will continue until mining ends in each Phase to re- move any stormwater or leakage that accumulates in the mining L.G. EVERIST, INC - WEST FARM RESERVOIRS November 2022 4 MINING PLAN AND TIMETABLE EXHIBIT D(CONT) areas and facilitate certification of the slurry wall. The area being permitted and much of the surrounding areas has historically been used as irrigated and non -irrigated cropland and vacant land. This site lays adjacent to the South Platte River, so it contains an alluvial gravel deposit in the eastern area, which extends west into a large terrace of gravel on the western areas. All mined areas will be reclaimed as ground water storage reservoirs using slurry wall liners. CURRENT CONDITIONS Large portions of the land to be permitted are currently operated as an irrigated farm, or used as rangeland. There are two rental houses and various barns and sheds in Phase 1 that are owned by the operator and will not be disturbed by mining. How- ever, the owner may choose to remove these at any time. There are various oil/gas lines and facilities on the permit area and 6 wells in Phases 3 & 4 that have been "shut in" and will eventually be plugged and abandoned. The oil and gas facil- ities will be removed by the producers and the supporting feeder lines will be abandoned and removed if they lie within the areas to be mined. They are shown on EXHIBIT C - CURRENT CONDITIONS MAP and EXHIBIT C-2 - STRUCTURES, but left off of EXHIBIT C-1 - MINING PLAN MAP and EXHIBIT F - RECLA- MATION PLAN MAP because they will be removed prior to mining those areas. If they remain when mining starts in those areas, a Tech- nical Revision will be filed to show how LGE will deal with them. Where needed, the active farm facilities and support struc- tures, i.e. water wells, sprinkle pivots, distribution ditches, pipes and diversion structures will be removed as mining pro- gresses. There are no County Roads or public facilities on the permit area. The oil and gas facilities lying outside the slurry walls will not be disturbed by mining. EXHIBIT C- CURRENT CONDITIONS MAP, shows the outline of the Affected Lands/permit area, the adjacent landowners within 200 feet of the facility, current topography, hydrologic and surface features of the property. Of particular note, along the South Platte River the permit/affected lands line is established one -hundred (100) feet west and parallel to the top side of the west bank along the South Platte River. Over the years, it appears this bank has been lined in places with armoring materials by previous landown- ers. No mining will take place within a minimum of 250 feet from the river bank that exists at this time. The initial access to the site is via an existing Private L.G. EVERIST, INC - WEST FARM RESERVOIRS November 2022 5 MINING PLAN AND TIMETABLE EXHIBIT D(CONT) Road located on the east side of CR 21 and approximately 1.37 miles north of Highway 66. In most cases, existing farm roads within the permit area will be used for mining needs and existing farm entrances on the paved roads will be used to cross the pub- lic ROW's. The initial Plant Site will be located on approxi- mately 50.00 acres of Phase 4, located on the southeast corner of CR 21 and CR 32.5. This Plant Site will be used throughout the life of the mine, as material will be conveyed or hauled to the plant from each Phase. In the future, 2 conveyor crossings may be installed from the northern area to the southern area. These crossings will be self-contained clear span units over CR 32.5 with all support structures to be built outside the road ROW's, but within the affected lands. They are part of the approved Platteville Devel- opment Plan and this would only happen after LGE has filed and received approval for a Technical Revision with the Division that would include showing the proposed location and design details for the crossings. The approximate proposed locations are shown on EXHIBIT C-1 MINING PLAN MAP . The phase access roads will be constructed of gravel ob- tained from on site. They will be at least 20 feet wide and graded to allow for drainage into the site and have ditches as necessary to collect runoff. Any runoff from the roads will be retained on -site and allowed to soak into the ground or evapo- rate. The roads will be maintained as needed. Access roads will be built around each water storage reservoir to provide access during mining, reclamation, and after release. The access roads will remain when reclamation ends as they will be used to access the property. GEOLOGIC SETTING The affected lands are located along the South Platte River in a Quaternary age, Piney Creek alluvial deposit. The eastward dipping beds of upper Cretaceous age Laramie formation are over- lain at an angular unconformity, by the Piney Creek alluvium. The sand and gravel encountered in the Piney Creek alluvium are a result of water erosion and redisposition of rock materials from the Front Range of the Rocky Mountains. The deposition of this material occurred during a time when the river was much larger than it is now. But, judging from the scarcity of large rocks found at the location, the velocity of the river must have slowed L.G. EVERIST, INC - WEST FARM RESERVOIRS November 2022 6 MINING PLAN AND TIMETABLE EXHIBIT D(CONT) sufficiently to have dropped boulders and most large cobble be- fore it reached this point. This type of material is typically found from south of Denver to the Colorado state line along the South Platte River. The thickness of the gravel deposit in West Farm Reservoirs varies from 27 to 75+ feet and the average depth is approximately 50+ feet. This site has a 10 to 12 inch layer of topsoil, con- sisting of loam and zero to 5 feet of a clay loam to sandy clay loam overburden. The alluvium is a well -sorted gravel, sand and silt, predominantly granitic and quartzite material with minor amounts of gneiss, schist and sandstone. The bedrock under the surface gravel is part of the Laramie formation and is a grey to grey black shale that is impervious. SOILS AND OVERBURDEN The information presented in this section is an overview of the Soils and Overburden types, quantities and depths found throughout the property, and also how these materials will be integrated into the mining and reclamation plans. The informa- tion has been obtained from the National Resource Conservation Service (NRCS) website, and from drilling reports. The NRCS Soils Report and SOILS MAP INEXHIBIT I/J, show the soil types delineated in the permit area and will provide background levels for the site as reclamation begins on the entire area. There are seven (7) types of soils found on the site. These soils are typically found throughout Weld County. They have no unusual qualities. The soils are designated as map Units 3, 10, 21, 22, 39, 41 and 68. Soil unit 68 lies along the slope from the upper level to the lower level that will not be mined. The NRCS report contains detailed information including the soils description, and chemical, physical, and engineering qualities. he depths of the topsoil and overburden, shown in the following table, is from a drilling report on the property.

The excess topsoil and over- burden will be used on site for reclamation or removed from the site The soils on the permit area that will be salvaged and re- placed should be capable of growing vegetation consistent with what is required by the Reclamation Plan. Enough topsoil will be retained to place an average of 10-12 inches on the areas to be revegetated. As each area is stripped, L.G. Everist will deter- mine how much soil will be needed to reclaim the area and it will be stockpiled for use in reclamation. Over the life of the mine, an estimated 588,400 yards of topsoil will be stripped from the mined area but, a minimum of 60,200 yards will be retained for resoiling the areas to be revegetated. In addition, there is from 0 to 3 feet of overburden on most of the site. Much of this overburden will be retained and used to backfill the reservoir slopes and used during slurry wall construction or removed from the site. The topsoil and overburden stockpiles will be located around the excavation, typical pile locations are shown on the ExHIBITC-1- MINING PLAN MAP. If the soil stockpiles remain undisturbed for more than one year, a cover crop of the approved seed mix, at the rate L.G. EVERIST, INC - WEST FARM RESERVOIRS November 2022 8 MINING PLAN AND TIMETABLE EXHIBIT D(CONT) called for in the EXHIBIT E -RECLAMATION PLAN, will be used to revegetate them. MINING PLAN This mining plan is designed as a two -stage startup that will allow for issuance of the permit at a lower initial bond. Operations Stage A covers the preparation of the Plant Site area. Operations Stage B will cover full implementation of the mining plan. A Technical Revision for a bond increase will be filed prior to starting Operations Stage B that will allow construction of a slurry wall, land stripping and mining in the first mining Phase and covers the Operations Stage A disturbed area. OPERATIONS STAGE A Activities during this stage of startup would allow for de- velopment of the permanent Plant Site to be located in Phase 4. It will cover the northern 50.00 acres of Phasel and will include stripping, salvaging topsoil and overburden, and processing plant construction. As a part of this development a wash water set- tling pond and fresh water pond facility will be constructed in Phase 1 that covers approximately 6.0 acres. The Plant Site will contain the processing plant/stockpile area, equipment storage area, temporary overburden and topsoil piles, drying pads and other axillary uses needed at the mine. Processing equipment may include but is not limited to conveyors, crushers and screen plants. A scale and scale house will be built at the entrance and auxiliary uses may include a Concrete Batch Plant, an Asphalt Batch Plant and a recycling facility, that will be placed in the Plant Site Area. EXHIBITL- RECLAMATIONCOSTS contains the information needed to establish the Operations Stage A financial warranty amount and an analysis for the transition to Operations Stage B - full mining activities. OPERATIONS STAGE B Prior to full mine operations and the move into Phase 1 a Technical Revision will be filed to increase the financial war- ranty adequate to cover the mining plan as described in the fol- lowing text. The plan is to have no more than 205 acres ± of disturbance bonded to allow for flexibility during mining. This 205 acre area will include stripped, partially mined, partially reclaimed, L.G. EVERIST, INC - WEST FARM RESERVOIRS November 2022 9 MINING PLAN AND TIMETABLE EXHIBIT D(CONT) the Plant Site area, materials stockpile area, settling pond fa- cility and the slurry wall around future reservoir areas. As mining progresses across the property some parts of the property will remain undisturbed while other areas will be either stripped, mined, partially reclaimed or totally reclaimed. The ExHIBITC-1-MINING PLAN MAPprovides information of how the Phases will develop during mining. Initially the 205 acres would include having stripped and partially mined Phase 1, the 50 acre Plant Site and installed the slurry wall around Phase 1. Much of the 205 acres would be within the highwater line of the reservoirs that would be covered with water and would need no soiling or revegetation. This map shows the estimated location of the final slopes around the perimeter of the entire areas to be mined. The esti- mated reservoir highwater line, the top of mining slope and slurry wall locations are shown. It also shows the maximum work- ing face (highwall) for each Phase and the estimated cut/fill volume per foot to grade the highwall back to 3h to lv. No more than 1000 feet of total permanent bank sloping will be needed (500' on each side of highwall). This amount of disturbance may change as the mine develops but prior to exceeding the initial 205 acres, a Technical Revision will be filed to increase the bond and allow for more disturbance. Of the 472.40 acres ± in the permit area, approximately 388.12 acres ± will be disturbed by mining. Within the disturbed area 364.71 acres will be mined. The 23.41 acres of unmined area will be the setback margins between the slurry wall and the top of slope into the reservoirs. This area will contain roads for access to the reservoir areas during and after mining. ExHIBITF- RECLAMATION PLAN MAP shows how the reservoirs will be developed. As mining progresses a reservoir area will be sold and a condition of the sale may require LGE to permit the owner of the reservoir to start construction of facilities related to the res- ervoirs) - such as installation of pump houses, inlet/outlet structures, rip -rap, etc. This would only happen if the reservoir owner does not want to wait for DRMS permit acreage release of that Phase. In this case, L.G. Everist would have already re- claimed the reservoir phase (including liner certification, final grading of the reservoir slopes, and initial seeding), but the phase acreage is not yet released from the DRMS permit (due only to vegetation growth). L.G. Everist would file Technical Revi- L.G. EVERIST, INC - WEST FARM RESERVOIRS November 2022 10 MINING PLAN AND TIMETABLE EXHIBIT D(coNT) sions as needed to incorporate the changes. At any given time, mining and "concurrent reclamation" may be occurring in one or more phases to accommodate the blending of materials, the natural progression of mining from one Phase to the next. This concurrent reclamation allows for reclamation work being completed in one phase while mining begins in another phase. The "direction of mining" arrows on ExHIBIT C-1 -MINING PLAN MAP show the applicant's best guess on how mining will progress through the mine areas at this time. Natural ground conditions and un- foreseen circumstances may necessitate changes to the mining di- rection throughout the life of the mine. The RECLAMATION COST ESTIMATE -EXHIBIT L iS based on the Operations Stage A plan to bond for initial setup of the Plants Site and support facilities. Included is an estimate for the Operations Stage B where it is based on an estimated disturbance area when the Phase 1 has been open for a few years. The acreage disturbed may increase or decrease as mining progresses. If it increases, a Technical Revision will be filed to adjust the bond amount to cover the changed cost estimate. Mining will start on the southwest of Phase 1 and progress to the east and south until the mining limits are reached. This will leave an open working face across the Phase as shown on the MININGPLANMAP. This face will have a i/i:l slope and will be worked to the north, the exterior final slopes will be either con- structed using the overburden material or mined to allow for a cut/fill final grading method using the native sand and gravel. If mining ends prematurely, this working face will be reclaimed using a cut/fill sloping method instead of backfilling. On the exterior final slopes, if the cut/fill method is used the formula would be, (setback distance+(slope factor*Depth)). In Phase 1 as shown on the MINING PLAN MAP the vertical mining setback line from the slurry wall would be 25'+(1.25*50')=87.50'. If the back - fill method is used, then 12 feet of flat area will be created at the setback line before sloping begins. The method chosen at the time of reclamation will be based on the depth of the deposit. The Deere & Ault slope geotechnical stability report in the Ap- pendix, page 3 under Analytical Results has an explanation of where this sloping plan would be used. The setbacks to be used in each Phase are shown in the table on the EXHIBIT C-1 - MINING PLAN MAP. The aggregates will be removed and L.G. EVERIST, INC - WEST FARM RESERVOIRS November 2022 11 MINING PLAN AND TIMETABLE EXHIBIT D(CONT) stored on the Plant Site area in Phase 4 for processing. The plan is to use conveyors or off -road haul trucks to move the ma- terial from the working face to the Plant. As mentioned above, the proposed mining sequence may change due to unforeseen circumstances such as market conditions, varia- tions in the natural deposit, agreement restrictions with struc- ture owners, etc. At this time, the plan is to mine them sequen- tially from 1 through 4 as shown on the maps. The following mining methods will apply to all of the reser- voir Phases. Operations will beginin each Phase of reservoir construction by stripping the area where mining will start. Ini- tially a 30 acre area will be stripped and periodically as min- ing progresses it will be extended so there is approximately 30 acres ready for mining at any -one-time as each Phase is mined. The topsoil needed for resoiling the above -water areas will be separated from the overburden and stored around the mining area for use in reclamation. Once enough topsoil is salvaged to resoil the above -water disturbed areas with an average of 10-12 inches, the rest may be sold. These stockpiles will be placed strategically as mining progresses. In some cases the stripped topsoil will be placed on areas where grading and shaping, are complete so it only has to be handled once. In Phases 1 and 2, all topsoil storage piles will be located as far from the river as practical, and will run parallel to the river's flow if lo- cated in the floodplain. During the stripping, a slurry wall pad will be built around the reservoir mining area using the excess topsoil and overbur- den. When the slurry wall pad has been completed, the bentonite slurry wall construction will begin. This is done by excavating a trench in the pad that is keyed into the underlying bedrock and filled with a mix of overburden, bentonite and water to create the slurry that becomes the liner. The soil and overburden not used in slurry wall construction or sloping will be placed around the mined area or sold. After the slurry wall liner is in place within a phase, a dewatering trench will be excavated inside the perimeter of the slurry wall. A pump will be installed and dewatering will begin. This will allow the area within the slurry wall to be dry mined. The trench will be extended around the area as mining progresses. Some of the soil will be used to construct a sight berm along road areas in each Phase. These berms will limit visibil- L.G. EVERIST, INC - WEST FARM RESERVOIRS November 2022 12 MINING PLAN AND TIMETABLE EXHIBIT D(CONT) ity into the active mining areas from the transportation corri- dors. The berms will vary in height depending on the area to be screened, with 3:1 slopes on each side and revegetated using the approved seed mix. The active mining area in the reservoirs will remain dry. After mining is completed, final reclamation of the phase can be completed, including liner certification, final grading of slopes and initial seeding for revegetation. Dewatering as mining progresses, facilitates early testing of the slurry wall liner, this is required to receive liner ap- proval certification from the State Engineer's Office in the Di- vision of Water Resources. In general, mining will commence in Phases 1, 2 & 4 on the south end and work north as shown by the arrows on the MINING PLAN MAP. In Phase 3, mining will start on the north and work south. The maximum length and cut/fill volumes of the working face and side wings in each stage are shown on the MININGPLANMAP. The mining setbacks will vary from the permit boundary and structures as allowed by each agreement for said structures and/or the Geotechnical Stability Analysis. This analysis shows that using the 25 feet setback from the slurry wall is adequate to meet the factors of safety in the DRMS Rules and Regulations, (see D&A Slope Stability Factor of Safety Results Summary Table on Page 4 of their report). The proposed setbacks are shown in the Setback Table on EXHIBIT C-1 - MINING PLAN MAP The material will be mined using loaders and excavators (track hoes) to remove material from the face. The material will then be delivered to the Plant for processing using haul trucks or a conveyor system. No blasting will take place at this mine. Reclamation will run concurrent with mining to control the amount of disturbed area in the mine at any -one-time. Reclamation begins in an area once the section is fully mined, and large enough for efficient reclamation (backfilling, compacting, slop- ing, soiling, etc.) that will not have to be re -disturbed. This pit will be operated year -around by L.G. Everist, Inc., weather permitting. There may be periods when the demands for material are slow and no mining will take place, creating an in- termittent operation situation. Areas not included in the bonded area will remain in agri- cultural production and the responsibility for weed control and agricultural area maintenance is retained by the landowners. L.G. EVERIST, INC - WEST FARM RESERVOIRS November 2022 13 MINING PLAN AND TIMETABLE EXHIBIT D(CONT) Please refer to the MININGTIMETABLE for the estimated acreage of each area associated with the mining part of this operation. Mining equipment may include but is not limited to, front-end loaders, scrapers, excavators, a drag line, dozers, off -road haul trucks, dump trucks and a water truck. Most of the water used on site will be for dust control used on haul roads or with sand and gravel processing. Please refer to EXHIBITG-WATERfor the discussion of how water will be used at the site, the estimated yearly needs, and the source(s) of said water. Prior to mining into the groundwater table, the appli- cant/operator/permittee will obtain a Substitute Water Supply Plan approval from the Division of Water Resources. All interior pit slopes will be maintained, when actively mining, with a pit -ward attitude to prevent off -site stormwater runoff. The general slope of reclaimed areas will be graded in a similar way so that stormwater drains into the site, not out. This same slope management plan will prevent any offsite erosion or other disruptions. In addition to the pit and reclamation sloping, isolation berms or ditches will be constructed around the mine as needed to prevent off -site stormwater from contacting the on -site disturbed areas. All stormwater contacting the dis- turbed area will be retained on -site to be discharged as part of the Colorado Discharge permit or allowed to evaporate or soak into the underlying gravel. The applicant had a jurisdictional delineation of the site conducted by environmental consultants and submitted to the U.S. Army Corps of Engineers (USACE). The Corps has determined that there are no jurisdictional wetlands on the West Farms site. The Corps determined that irrigation return flow ditch on the west side of Phases 1 and 2 is jurisdictional and must remain. So the ditch may be slightly improved by defining its course, but it will remain and not be impacted by the mining operation. If the irrigation ditch dries up once the area is no longer irrigated, the applicant may request a change in status (for the ditch) from the Corps. MINING TIMETABLES This estimated mining timetable is based on an average year, and L.G. Everist expects some years to vary widely from the aver- age. If there are changes in the mining timetable, we will dis- L.G.

EVERIST, INC - WEST FARM RESERVOIRS November 2022 15 RECLAMATION PLAN AND TIMETABLE exhibit E EXHIBIT E RECLAMATION PLAN AND TIMETABLE OVERVIEW The proposed future use is to create 4 in -ground, developed water storage reservoirs with a vegetated border around the highwater lines of each reservoir. Each of the proposed reser- voir areas will be sealed with a slurry wall liner. Eventually the reservoirs will be sold to a municipality or water company who will be responsible for the construction of any additional reservoir operations facilities (pump houses, inlet/outlet struc- tures, etc.) on each reservoir. This will occur once L.G. Everist, Inc. has resoiled and seeded the perimeters. (If the facilities construction is anticipated prior to the release from the DRMS permit on a Phase, a Technical Revision will be filed to add the locations of any reservoir facilities to be built.) The reclamation methods and plans described below will apply to all Phases but may require minor variation depending on the conditions found in each Phase. Reclamation will run concurrent with mining so it will commence as soon as enough area is avail- able to reclaim and not be redisturbed. The setbacks and side slopes from the water's edge to the slurry wall or setback limit will be resoiled and revegetated using the methods described in the following plan. On -site generated inert material will be placed in backfill areas or will be recycled/sold. The existing oil and gas wells shown on MAPExHIBITC are all shut-in, meaning they are on the list to be plugged and abandoned in the future. Once the wells are removed, all of the support facilities will be removed and the feeder lines abandoned. This reclamation plan assumes they will be removed prior to mining in the areas they affect. Should the O&G facilities still exist when mining reaches them, a Technical Revision will be filed to show how they will be mined around and reclaimed. The applicant proposes bonding the site in two Operations Stages. For Operations Stage A, the initial bond is calculated on having only the Plant Site and settling ponds bonded until mining is ready to start in Phase 1. Upon competition of prepa- ration of the Plant Site a Technical Revision would be filed to increase the bond to allow for full development of the mine as explained below. This second bond would be to cover the maximum amount of disturbance throughout the mine (205 acres), this would including a sufficient length of liner construction and bank sloping, the Plant Site, areas of seeding, backfilling, etc. If the applicant determines that the amount of disturbance at the mine may soon L.G. EVERIST, INC. - WEST FARMS RESERVOIR November 2022 16 EXHIBIT E RECLAMATION PLAN (cow) exceed the bonded amount, the applicant shall submit a bond revision to the Division. Currently, the proposed mine site is primarily irrigated agricultural land, but is broken into 4 different use areas. The current uses are, irrigated crop areas; non -irrigated pasture; ditch and return flow corridors; and oil/gas operations areas with some high capacity gas pipeline ROW's around the perimeter. The agricultural uses will continue in areas where mining opera- tions have not yet begun. There is very little native vegetation present on the majority of the site because of the intensive agricultural practices that have taken place on the land. In most cases, the oil/gas operations areas have little vegetation and the high pressure gasline ROW's have been farmed for many years and the vegetation cover on those areas is consistent with farmed areas. The ditch and return flow corridors have been disturbed by ditch maintenance over the years. This leaves only isolated areas around the permit area with vegetation that may be considered native. The typical vegetation descriptions in ExHISITSI &Jwill not match the actual current vegetation on the site due to the agricultural activities - pastureland (cattle grazing) and farming with various crops. RECLAMATION PLAN This section covers reclamation on the developed water storage reservoirs in Phases 1 thru 4. As discussed in the MINING PLAN text, reclamation will run concurrent with mining. Initially this will happen when the reservoir slope areas are being mined and graded. The plan is to either leave undisturbed natural sand and gravel at can be cut/fill graded 3v:lh or to use overburden to create compacted slopes around each reservoir. The APPENDIX contains the Deere & Ault Geotechnical Slope Stability Analysis where on page 4 they explain when and how each method will be used. If cut/fill sloping is used, the upper part of the slope area will be pushed into the lower part. If backfilling is done, then once mining has reached the outer limit, the stripped over- burden will begin to be placed against the working face so only minor amounts of slope work will be necessary as mining ends. No more than 1000 feet of outside bank backfilling and sloping will be needed at any given time. This will also ensure, that if mining ceases before the resource is exhausted, only a minor amount of work would have to be done to finish reclamation on the disturbed area. The temporary topsoil and overburden stockpiles L.G. EVERIST, INC. - WEST FARMS RESERVOIR November 2022 17 EXHIBIT E RECLAMATION PLAN (cow) in the various mining phases will be available for reclamation needs Armoring in Phase 2 (located north of CR 32.5) along the river will progress with sloping so no more than 1000 feet will need to be completed at any time. The BANK ARMORING PLAN is in the APPENDIX and explains how and where the armoring will be placed. There are no plans to install Inlets or Outlets for the reservoirs. Those will be the responsibility of the reservoir developers. LGE will be working with the Town of Platteville for directions on Flood Plain development. This facility is not in an Urban Area, not near public land, or facilities where public safety is a concern so, inlet/outlet structures for private reservoirs are not needed. When grading and shaping is completed on a large section of reservoir banks, the areas above the high water line will be resoiled and then seeded during the next seasonal planting win- dow. The EXHIBITF-RECLAMATIONPLANMAP shows the sloping plans, the area to be revegetated and areas that will be reservoirs in this plan. All reservoir bank sloping will be completed to the stated 3:1 slopes or flatter. All areas that are above the high water line, and are not being reclaimed as graveled access roadways, will have an average of 10-12 inches of soil placed and prepped for seeding. All top soiled areas will be seeded with the seed mix described in this plan, and effective weed control measures will be implemented until the Phase is released from the permit area. GENERAL DISCUSSION There are sufficient amounts of topsoil on the site so the mined areas can be resoiled to an average depth of 10-12 inches. Sufficient topsoil will be saved for use in reclamation. The available topsoil to be salvaged from the stripping process will preclude having to haul additional soils onto the site for revegetation. The existing soils on the property have been capable of producing healthy crops and grasses and are expected to work well for revegetation of mined areas. The vegetation information was obtained from site visits and data provided in the NRCS Web Soil Survey page. A copy of that report is in ExHIBITIANDJand describes the current soils and vege- tation on the properties in more detail. As outlined in the EXHIBITD-MININGPLAN, approximately 388.12 acres ± of the permitted area will be disturbed as a result of mining activities. Once mine development begins, the plan calls for the initial bond to have 205.00 acres± disturbed at L.G. EVERIST, INC. - WEST FARMS RESERVOIR November 2022 18 EXHIBIT E RECLAMATION PLAN (coNv) any -one-time and the disturbed area may be divided between the reservoir Phases and the Plant Site in Phase 4. As mining pro- gresses across the property, some parts of the property will remain undisturbed while other areas will be either stripped, mined, partially reclaimed or totally reclaimed. The EXHIBITC-1 - MININGPLAN MAP shows how the pit will be developed. The EXHIBIT F- RECLAMATIONPLAN MAP show how the area will look when reclamation is complete. Careful analysis of the growth medium and salvageable soil will permit the operator to carry out a soil additive program and to monitor the prescribed seeding plan to determine if the plan requires revision. Under normal weather conditions, an adequate moisture reserve will be present for establishment of the pro- posed seed mixture. No irrigation is planned for the reclaimed areas. No revegetation will take place on undisturbed areas, roads or oil/gas operations access roads or facilities. The reclamation timetable shows the types and amount of land use in each Phase when reclamation is complete. Approximately 19% of the area in the permit will not be disturbed by mining, either because it is setbacks around the permit line, gasline ROW's, along the ditch and areas too small to mine that will be kept in their natural state. REVEGETATION PROGRAM The revegetation program to be implemented on the areas to be seeded with grass by L.G. Everist is detailed below. The topsoiling plan presented above and this revegetation program are devised after careful review of the existing soil conditions and present vegetation, both on the site and in the NRCS report. "Revegetation will be carried out in such a way so as to estab- lish a diverse, effective and long-lasting vegetative cover that is capable of self -regeneration without continued dependence on irrigation, soil amendments or fertilizers.. (CRS 34-32.5-116 (4)(f)) The plan is designed to create a vegetative cover around the reservoirs that is at least equal in extent to the cover of natural vegetation before mining. The use of species native to the area are included. Since the intended use of the reclaimed land along the reservoirs is rangeland, any slopes created will be commensurate with this final land use. Seed will be drilled wherever possible, when drilling is not possible, the seed will be broadcast. The revegetation plan provides for the greatest probability of success in plant estab- lishment and vegetative development by considering environmental factors such as seasonal patterns of precipitation, temperatures L.G. EVERIST, INC. - WEST FARMS RESERVOIR November 2022 19 EXHIBIT E RECLAMATION PLAN (cow) and wind. Other considerations, such as soil texture, fertility, slope stability and the direction in which slopes face, have been considered. A weed control plan is included in this submittal, see the APPENDIX. Graveled maintenance roads will be built around each reser- voir and around each gas/oil wells, should any remain, where no seeding or resoiling will take place. This will provide room around each well or reservoir to service it as needed by the well or reservoir owners. These access roads and graveled areas are shown on EXHIBIT F - RECLAMATION PLAN MAP . SEEDBED PREPARATION When mining on an area is complete or there is room to begin reclamation, any compacted areas will be ripped and scarified to created a deeper root zone under the resoiled areas. Once this is complete, the stockpiled soils will be spread. If tests show a fertilizer is needed, it will be broadcast spread on the seed- bed at an adequate rate suggested by NRCS or a seed- ing/revegetation contractor. On the areas where seed is broad- cast, the surface will be left fairly rough to trap the seed and keep it from being affected by wind. SEEDING TIME The grass seed mixture will be planted from early fall through spring (October through May). The time of planting will be controlled by when the resoiled areas are ready for planting. If fall planting is convenient, the seeding will be done before the first freeze (about the time Winterwheat is planted). If spring planting is called for, it will be done in March or April, weather permitting, after the last frost. Both periods assure there will be adequate residual ground moisture available for the newly planted seeds. GRASSES The following seed mix was developed by the NRCS office in Brighton many years ago and is used on all L.G. Everist mining operations in Weld County. It has proven to be very reliable. This mix will place approximately 41.2 seeds per pound per sq-ft as prescribed by the NRCS planting guidelines. If the seed is broadcast, the amount will be doubled and spread on a rough surface. The seeded areas will then be dragged or raked thor- oughly to set the seed. Under normal conditions, the operator will strive for a 30 to 40 percent cover rate on the grass revegetated areas when reclamation is complete. L.G. EVERIST, INC. - WEST FARMS RESERVOIR November 2022 20 EXHIBIT E RECLAMATION PLAN (see) No trees will be planted, because they are not compatible with reservoir development as their root systems affect the liners. It is expected some natural invasion from adjoining areas will occur. PROPOSED SEED MIX Western Wheatgrass (Aribba) 5.0 Big Bluestem (Champ) 2.5 Blue Grama (Hachita) 0.6 Switchgrass (Blackwell) 1.75 Total 9.85 It has been our experience on other operations, that the seeded area may have a heavy cover of weeds after the first year. The second year, there are fewer weeds as the grasses start to take hold. By the third year the weeds are mostly gone and the grass has established itself so it will grow in future years. These weeds also tend to shade the seedbed, retain snow in the winter and act as a wind break for the newly emerging grasses. The area will then be monitored for success of revegetation until it is released from the permit area by the Mined Land Reclamation Board. WEED CONTROL The revegetated areas will be monitored closely each spring for the first two years to determine if noxious weeds are invad- ing the area. L.G. Everist, Inc. will implement a weed monitor- ing and control plan that covers the areas actively used by their operations. Weed control on the agricultural use areas will be the responsibility, as covered in the lease, of the farmer using the land. LEG understands their responsibility for weed control on th permit area and will work to have the farm lessee perform weed control on non mining areas. Weed control in the mining and reclamation areas will be initiated if the problem becomes serious or if an excessive weed cover is still present at the end of the second year. In no way should this be taken to mean that L.G. Everist will try to eradi- cate all the weeds from the site. Some weeds are beneficial to the upland game species in the area, they provide important protection from the elements during winter, and nesting sites during the spring. Total eradication of weeds from the site is L.G. EVERIST, INC. - WEST FARMS RESERVOIR November 2022 21 EXHIBIT E RECLAMATION PLAN (corar) not necessarily desirable or possible, so we will be using stron- ger controls on the noxious weeds and controlling the rest as needed. Weed control may be done through mowing or chemical means. Control of noxious weeds is important to the state, so we will follow USDA Extension Service recommendations to control them. Our Weed Control Plan is included in the APPENDIX. IRRIGATION No irrigation is planned for the revegetated area around the reservoirs. It makes the vegetation dependent on water and does not promote a vegetation cover that is diverse and capable of self regeneration. RECLAMATION PERFORMANCE STANDARDS (The following information is presented to address specific parts or Rule 3 as required by the MLRB Rules and Regulations.) L.G. Everist, Inc intends to operate the mine in compliance with the Reclamation Performance Standards of Rule 3. Grading will be done to create a final topography that is compatible with the intended final land use. The slope in the developed water storage reservoirs will be mined to their final slopes. These slopes will be 3:1 or shallower and on the unmined areas they will remain in their current configuration in an attempt to retain the present drainage pattern across the property as much as possible. A mine entrance sign that conforms to the requirements in Rule 3.1.12 (1996) will be installed at the entrance to this facility prior to commencement of mining. The material used to create the slopes will be native mate- rial found on the site. It will consist of sand, gravel, over- burden and topsoil. The Phases will be reclaimed so that a suitable grade for drainage exists. All surface runoff within the mine site will be directed into the excavated area, and all surface runoff outside of the permitted area will be allowed to flow into natural existing drainages outside the site. All grading will be done in a manner to control erosion and to protect areas outside the affected lands. All backfilling and grading will be completed as soon as feasible after mining is completed. All refuse will be hauled away or disposed of in a manner that will control unsightliness and protect drainage systems from pollution. L.G. EVERIST, INC. - WEST FARMS RESERVOIR November 2022 22 EXHIBIT E RECLAMATION PLAN (cow) There are no acid-forming or toxic materials inherent in the sand and gravel deposit. If petroleum products are stored at the site for mining equipment and operations, they will be stored as prescribed by applicable laws. Any storage tanks will be surrounded by a berm or be of the latest multi -wall construction, adequate to contain any fluid spilled, should a tank rupture. In addition, there is adequate absorbent materials on site to contain any spills that would occur. There are no drill or auger holes on the land. Maximum slopes within the mined area will be within the limits set forth in the Rules and Regulations of the Board and will be capable of being traversed by machinery. The slopes between the eastern and western reservoirs will remain undis- turbed and in their natural state, slope and appearance. The operator does not expect prevailing hydrologic condi- tions to be disturbed. L.G. Everist will comply with applicable Colorado water laws and regulations (as the operator understands them) which govern existing water rights. The operator does not expect to adversely affect the prevailing hydrologic balance of the affected land and surrounding areas. Nor does the operator expect to affect the quality of water in surface and ground -water systems both during and after the mining operation and during reclamation. In addition, the operator shall comply with appli- cable Federal and Colorado water quality laws and regulations. Any water used in the mining operation and the processing plants will come from water owned or leased by L.G. Everist and legally suitable for use in mining operations. EXHIBIT G - WATER INFORMATION contains specific information concerning impacts and uses of water at this mining operation. No dredging takes place at this facility, there are no temporary siltation structures involved in this operation and no mining will be done in a river or waters of the United States. A U.S. Army Corps of Engineers 404 Permit is not required for this operation because there are no jurisdictional wetlands on the site. The operator has filed a RGP-5 from the Corps for the relocation of 1 irrigation return flow ditch in Phase 1, along the eastern side of the phase. Temporary settling ponds will be constructed on the site to collect water from the material washing at the processing plant. The settling ponds will be removed during final reclamation. The fines in the wash -water settle out in the ponds and the water is then recirculated to be used again in the processing plant. There will be no earthen dams on the mined area. L.G. EVERIST, INC. - WEST FARMS RESERVOIR November 2022 23 EXHIBIT E RECLAMATION PLAN (cow) Groundwater collected from the dewatering trenches may be discharged from the site, after any natural fines have settled out. The discharged groundwater quantities will be measured and sampled as per the requirements under a CDPS - Sand and Gravel Mining Process Water and Stormwater Combined Permit. The mining and reclamation plans have taken existing wild- life conditions into consideration. The final reclamation will enhance the area for wildlife use. The mining and reclamation plans allow for the safety and protection of wildlife remaining on the mine site, at the processing site and along all access roads on the site. In practice this is done by limiting the amount of disturbance, restricting truck and equipment speeds to 15 mph or less and doing concurrent reclamation. Mine employees are trained to deal with wildlife found on the mine, during operating hours to avoiding harming them. See ExHIBITH-WILDLIFE for more information. As mentioned previously, topsoil on the mine area is of good quality, so it should be a decent growth medium for reclamation. When topsoil is removed, to reach the sand and gravel deposit, it will be segregated and stored in graded stockpiles, generally located in areas where disturbances by ongoing mining operations will be at a minimum, i.e., along setbacks on the pit perimeter. If the topsoil (and overburden) stockpiles remain undisturbed for more than a year, the approved seed mix will be applied to pre- vent erosion, to control weeds, and to keep them viable for reclamation. Fertilizer and other soil amendments may be used as discussed in this plan. If revegetation problems occur before release, an analysis of the problem area will be done and the area will be revegetated again as necessary. The seed mixture and rates may be revised as needed to complete reclamation, if a substantial modification is required, the Division will be notified prior to making the change. This gives us the most flexibility to complete reclama- tion successfully. RECLAMATION TIMETABLE Reclamation will begin once enough area has been opened so that any reclamation completed will not be disturbed as mining progresses. This may take 5 or more years depending on the economic conditions in the area and the amount of material mined. The operator anticipates approximately 81% of the total mined land will be reclaimed by the time mining is completed. L.G.

Please refer to EXHIBITB-VICINITYMAP for the property configuration and the relationships to surrounding geological features. The site is bordered on the south, west and northwest sides by irrigated agricultural lands and on the east and part of the northeast side by the South Platte River. There are no ditches that cross the property but, on site temporary feeder ditches carry water to the fields being irrigated. Two center pivot irrigation systems are fed by wells owned by L.G. Everist, Inc. There are 7 registered irrigation wells, one domestic well and 6 piezometers on the property. Within 200 feet or the permit line there is 1 Domestic and one Geothermal wells located in the southwest corner of the site. Based on regional groundwater studies and the experience gained by L.G. Everist, Inc. during numerous previous permit applica- tions they have found that slurry wall liners mitigate any im- pacts to groundwater on nearby areas surrounding a lined reser- voir. Ground water in this area tend to flow from the west towards the river, the depth to water on the flood plane level averages 6.9 feet below the surface and along the western terrace deposit the depth to the water table is 23 feet. Data for the monitoring well information collected thru the month of submittal is shown on TABLE G-2 ON SITE GROUND WATER MONITORING DATA . If any significant groundwater changes do occur, they can be mitigated as discussed below. Potential Water Resource Impacts Ground Water Wells We expect this mining operation will have no or minimal impacts on the prevailing hydrologic balance. Sand and gravel mining related impacts to groundwater wells near the pit will be mitigated through the installation of slurry walls around the perimeter of new reservoir mining phases prior to the start of dewatering in each reservoir phase (see EXHIBIT D -MINING PLAN) . TABLE G-1 WATER WELLS WITHIN 200 FEET i S a list Of 12 wells from the Office of the State Engineer's files that are located within 200 feet of the permit area. (NOTE: THE WELL PERMIT LOCATION SHOWN IN THE TABLE HAVE BEEN GPS LOCATED BY THE STATE ENGINEERS OFFICE'S AND GROUND VERIFIED) . All wells except the geothermal well (Blue highlight) are shallow wells, at this time, there is one shallow well within 200 feet of the permit area that is not owned by L.G. Everist, Inc. The Palombo domestic well is located near the southwest corner and is up gradient from the mining area. LGE owns the 8 wells listed L.G. EVERIST, INC. - WEST FARM RESERVOIRS 28 November 2022 Exhibit G Water Information (cont) for Norgren Farms and is in the process of filing a name change. There are 2 monitoring wells along WCR 32.5 owned by Metro Wastewater Reclamation District, the eastern most one is more than 6Oo feet from the permit line. Prior to exposing groundwater or installing a slurry wall liner in any permit area, a well survey will be performed on any shallow wells within 200 feet of the phase. Wells that are located within 200 feet of the permit area, that do not need to be tested are(a) owned by L.G. Everist, Inc., (b) monitoring wells, (c) deep wells, because deep wells will not be affected by potential surface impacts due to mining. L.G. Everist will attempt to obtain for each shallow well to be tested the following data: Basic Well construction data that is currently available. Total well depth Depth to static water level, Depth of pump intake Conduct pump test to determine well yield (subject to DWR Regulations) Conduct analytical sampling of all Domestic Drinking Water parameters for any residential wells. All data collection will be completed at L.G. Everist's expense. Data will be provided to DRMS and the well owner upon their request. If a well owner chooses not to allow the permittee access to collect the above data, they will be provided with a form that they can sign and date to document that they have been provided with an opportunity to have their well characterized at the permittee's expense, but have chosen to decline to participate. L.G. Everist, Inc. has installed 6 piezometers (a.k.a. Monitoring Wells) around the mine. Their locations are shown on the maps and on MAP ExHIBIT G-1 WELLMAP. L.G. Everist started data collection in July 2019 and will do monthly readings throughout the life of the mine. We will provide a summary of the data yearly with the Annual Report. Mitigation Trigger Starting in July 2019, L.G. Everist, Inc. began to collect groundwater elevations from newly installed monitoring wells on and around the mine area to establish historic ground water elevations around and on the site. The period July 2019 until installation of the Phase 1 liner will be used as the baseline for triggering mitigation actions. The baseline data needed for the L.G. EVERIST, INC. - WEST FARM RESERVOIRS 29 November 2022 Exhibit G Water Information (cont) areas are in place well before installation of the slurry walls will begin. The permit area has two area where the depth below ground level area vastly different. The dividing line between these land features is a natural bank where the river valley transitions from the flood plane on the east side to the upland area along the west side. In the eastern area, Phases 1 and 3, the natural groundwater depths vary from 2.9 to 4.4 feet, average 3.5 ft. below the surface. On the western areas, Phases 2 and 4, the natural groundwater depths vary from 16.7 to 23.9 feet, average 19.5 ft., below the surface between June 2019 and October 2022. These ground water depths and averages may change prior to mining commencing. L.G. Everist, Inc's. experience on other mines in the South Platte River valley indicates that groundwater levels can fluctuate as much as 7.0+ feet depending on the season. The data collected confirms that the West Farm Reservoirs site is within a few inches of that number. In a normal mitigation trigger plan, the trigger limits would be set at as a three (3) foot plus or minus change over a 3 -month running average. Realistically, in this case the trigger number should be based on a 3 -foot change determined by a line that approximates an up or downward trend of the water table and considers outside impacts such as, drought, storm events or decreased irrigation activities. We do not expect this to be a problem where the slurry walls are in close proximity to a flowing water body like the irrigation return flow ditch that bisects the mine site north to south and the South Platte River along the east and north sides. The mining operation will have minimal effect on the South Platte River in the form of minor groundwater depletions due to evaporation and water uses associated with mining. The depletions to the South Platte will be mitigated thru a temporary Substitute Water Supply Plan (as required and approved by the Division of Water Resources) to prevent injury to the vested senior water rights. The reclamation plan proposes the creation of 4 slurry wall, lined reservoirs that will not be hydraulically connected to the South Platte River or any alluvial aquifer. The reservoir areas will be sealed prior to mining, thereby eliminating the groundwater draw down which is typically associated with mine site dewatering. This will also eliminate or minimize the possibility of any adverse impacts to the single nearby alluvial well. If during the course of mining or reclamation complaints from the well owner are received by the permittee, the permittee will commence an evaluation and investigation, including providing replacement water to the well owner if necessary, within 48 hours. L.G. EVERIST, INC. - WEST FARM RESERVOIRS 30 November 2022 Exhibit G Water Information (cont) DRMS shall be notified within two business days of the complaint and the proposed initial steps for the evaluation of the complaint. A written report will be submitted to DRMS within 30 days detailing the information collected during the investigation of the complaint, and proposed mitigation activity, if required. Post Reclamation Any slight groundwater mounding and shadowing associated with the slurry wall sealed portions of the pit are not anticipated to produce any adverse impacts to adjacent properties. Potential groundwater mounding around the mine will be mitigated by the South Platte River and the single irrigation return flow ditches surrounding the lined area. These existing water features will serve to regulate and balance groundwater elevations in the alluvium adjacent to the sealed pits. The operator does not anticipate any long-term post - reclamation ground water depletions, but if there are any, they would be replaced through a Colorado Water Court approved Plan of Augmentation. L.G. Everist, Inc. expects that prior to competition of the reservoirs a local government agency will purchase the storage rights and may begin final construction on the reservoirs. As water storage reservoirs are completed, they will be turned over to the purchaser for further development to complete the final features needed for developed water storage reservoirs. L.G. Everist will submit Technical Revisions to the DRMS if the purchaser makes changes prior to L.G. Everist receiving final reclamation approval and acreage releases from the Division. Discharge Permits Surface Water Management When necessary, ground water will be pumped and discharged from the West Farm Reservoirs mine under a CDPS Permit which the operator will obtain from the Colorado Department of Public Health and Environment, Water Quality Control Division (CDPHE-WQCD). This permit will remain active during the life of the mine. The discharge points may change as mining progresses and all necessary changes will be submitted to the WQCD for modifications to the discharge points. Runoff from disturbed areas will be managed and controlled to protect against pollution, of either surface or groundwater through the implementation best management practices which include sloping disturbed areas inward toward the site, vegetating berms and other disturbed areas, and other site -specific controls as needed. As per the State Engineers Office requirements all stormwater collected for treatment will be discharged within 72 hours after the storm event ends. L.G. EVERIST, INC. - WEST FARM RESERVOIRS 31 November 2022 Exhibit G Water Information (cont) Estimated Consumptive Water Use The annual consumptive uses of water for the Ragsdale Reservoirs mine are estimated to be: USES VOLUME Acre-feet 4o Moisture Loss in Materials (1.7 Million tons) 50.05 Dust Control 3.00 Water Surface Evaporation (10 ac) 23.80 Total Consumption (Augmented) 76.85 Substitute Water Supply Plan Ground water depletions associated with L.G. Everist's West Farm Reservoirs operation will be covered under a substitute water supply plan (SWSP) pursuant to C.R.S. 37-90-137, approved by the State Engineer's Office (SEO) for replacement of the ground water depletions due to mining. This plan will be updated and renewed every 2 years. The Applicant will maintain a SWSP throughout the life of the mine. After completion and reclamation of all lined reservoirs there will be no long-term evaporative depletions. However, if any unlined open surface water areas created by mining remain at the end of reclamation, then a court approved augmentation plan will be applied for before reclamation is complete. 100 -Year Floodplain Portions of the West Farm Reservoirs mine are located within the 100 -year floodplain of the South Platte River. The applicant will obtain a Flood Hazard development Permit from the Town of Platteville if needed. The location of the 100 -year flood line shown on the affected lands was transferred from FIRM Panel 08123C1905E, effective 1/20/16 to all maps. L.G.

Significant Wildlife Resources Much of the land to be permitted is used as an active farm with agricultural uses covering approximately 93.5%, buffers and farm yards cover 4.6%, oil & gas facilities cover 0.4% and water courses 1.5%. The species of wildlife found in the area around the property are those typically found on actively farmed areas such as turkeys, song birds, and duck and geese, as well as mammals such as skunks, mice, deer, fox, and coyotes. The larger game animals such as deer, fox, and coyotes are commonly seen along the South Platte River or in cultivated fields after harvest. In areas surrounding the water features crossing the site, there may be reptiles and amphibians. The smaller mammals and wildlife are usually found around the perimeters of the active crop lands and farm buildings wherever protective vegetation exists. No raptor nests were observed on the permit area however, an active Red -Tail Hawk nest was observed on an adjoining owners property approximately 500 feet south of the SE corner or the Affected Lands line. Since the nest is not in the permit area it will not be disturbed by mining. Seasonal Use Many of the mammals that may potentially be encountered on the mine are expected to be year-round residents, or will come and go depending on their mobility. The deer, fox and coyote are not movement -restricted and tend to travel through many properties as part of their natural daily routine covering several square miles. The water fowl, raptors and other birds may use the property year-round with some migrating in the spring and fall. Shorebirds may use the site during the spring, summer, and fall for feeding or resting during migration. The smaller mammals may be displaced initially, but with the amount of surrounding area that will not be disturbed they will find places in and around the active mining areas. Any amphibian and reptile species that may be present on the site could be year-round residents, since they would likely stay in the areas around the site's water features (ditch setbacks). Threatened and Endangered Species and Critical Habitat There are no threatened or endangered species on the permit area to our knowledge. A site review complete by Savage and Savage indicates there is no habitat for the Preble's meadow L.G. EVERIST, INC. - WEST FARM RESERVOIRS 36 November 2022 EXHIBIT H WILDLIFE INFORMATION (CONT) jumping mouse on the permit area. Areas near the irrigation ditches within the site have steep sides and do not have vegetative cover that is characteristic of Preble's habitat. Project Effects to Wildlife Existing wildlife in the area are not expected to be significantly impacted by mining at this site. Temporary and permanent losses of food and habitat are not expected to be significant as the area of disturbance will be limited to less than 305 of the permit area at any given time. Haul road speed limits will be limited to 15 MPH or less. There may be some displacement of smaller birds and mammals during active mining operations in a phase, but once a reservoir is developed it will increase the habitat for shorebirds and water fowl. The revegetated areas may become habitat for small mammals. There will be no mining within the river corridor area, therefore leaving a transit area for larger wildlife and scavengers along the river to bypass the mining area. The irrigation return flow area will also provide transit corridors through the mine as it develops. L.G. EVERIST, INC. - WEST FARM RESERVOIRS 37 November 2022 EXHIBIT I/J SOILS & VEGETATION SOILS INFORMATION The following information was obtained from site observations and the basic soils and vegetation information found thru the USDA's National Soils information page and the Soil Survey of Weld County. The soils information was downloaded from the USDA site and is made part of this application. Soil units are shown on the USDA map, reproduced on the next page. The photo map shows the surrounding vegetation features and soil types. As explained earlier in EXHIBITD-MININGPLAN, the mine site is located about 1.5 miles west of Downtown Platteville and is separated into a western and eastern area by an irrigation return flow ditch and north to south by Weld County Road(WCR) 32.5. The western border of the mine site parallels WCR 21. The area to be mined is west of the river and two-thirds of which lies in the 100 year floodplain of the river. The remaining, western third is a terrace deposit above the floodplain. This west area is predominantly used for crop production or general agriculture and grazing at this time. The areas on the level of the South Platte River have been used for irrigated crops, grazing, river bottom and private recreation. There are 7 soils types found on the mine site that will be disturbed by mining. In the lower terrace adjacent to the river where the site has been flooded in the past the topsoil depth varies from 10 to 12 inches, with lenses that may be deeper, averaging 12 inches. The overburden averages from 0 to 5 feet deep averaging 5.0 feet and the gravel varies from 27 to 55 feet deep, averaging 45.0 feet. On the western upland area the topsoil averages from 10 to 12 inches deep. Under laying the topsoil is a layer of overburden varying from 3 to 4 feet deep and a layer of gravelly sand that is 55 to 65 feet thick. There is adequate topsoil on the mined area to salvage enough to respread an average of 10-12 inches on all above water areas needing seeding for reclamation. Portions of the overburden will be used on -site for reservoir liner construction. Some topsoil and overburden may be sold as fill material. Detailed soils information can be found in the following soils descriptions and tables. The Water area (soil type 85) has no topsoil nor will it be mined. L.G.

The map unit descriptions, along with the maps, can be used to determine the composition and properties of a unit. A map unit delineation on a soil map represents an area dominated by one or more major kinds of soil or miscellaneous areas. A map unit is identified and named according to the taxonomic classification of the dominant soils. Within a taxonomic class there are precisely defined limits for the properties of the soils. On the landscape, however, the soils are natural phenomena, and they have the characteristic variability of all natural phenomena. Thus, the range of some observed properties may extend beyond the limits defined for a taxonomic class. Areas of soils of a single taxonomic class rarely, if ever, car napped without including areas of other taxonomic classes. Consequently, _ . _.; map unit is made up of the soils or miscellaneous areas for which it is named and some minor components that belong to taxonomic classes other than those of the major soils. Most minor soils have properties similar to those of the dominant soil or soils in the map unit, and thus they do not affect use and management. These are called noncontrasting, or similar, components. They may or may not be mentioned in a particular map unit description. Other minor components, however, have properties and behavioral characteristics divergent enough to affect use or to require different management. These are called contrasting, or dissimilar, components. They generally are in small areas and could not be mapped separately because of the scale used.

No aggregation of data has occurred as is done in reports in the Soil Properties and Qualities and Suitabilities and Limitations sections. The reports contain soil interpretive information as well as basic soil properties and qualities. A description of each report (table) is included. Land Classifications This folder contains a collection of tabular reports that present a variety of soil groupings. The reports (tables) include all selected map units and components for each map unit. Land classifications are specified land use and management groupings that are assigned to soil areas because combinations of soil have similar behavior for specified practices. Most are based on soil properties and other factors that directly influence the specific use of the soil. Example classifications include ecological site classification, farmland classification, irrigated and nonirrigated land capability classification, and hydric rating. Land Capability Classification The land capability classification of map units in the survey area is shown in this table. This classification shows, in a general way, the suitability of soils for most kinds of field crops (United States Department of Agriculture, Soil Conservation Service, 1961). Crops that require special management are excluded. The soils are grouped according to their limitations for field crops, the risk of damage if they are used for crops, and the way they respond to management. The criteria used in grouping the soils do not include major and generally expensive landforming that would change slope, depth, or other characteristics of the soils, nor do they include possible but unlikely major reclamation projects. Capability classification is not a substitute for interpretations designed to show suitability and limitations of groups of soils for rangeland, for forestland, or for engineering purposes. In the capability system, soils are generally grouped at three levels: capability class, subclass, and unit. Capability classes, the broadest groups, are designated by the numbers 1 through 8. The numbers indicate progressively greater limitations and narrower choices for practical use. The classes are defined as follows: Class 1 soils have slight limitations that restrict their use. Class 2 soils have moderate limitations that restrict the choice of plants or that require moderate conservation practices. Class 3 soils have severe limitations that restrict the choice of plants or that require special conservation practices, or both. Class 4 soils have very severe limitations that restrict the choice of plants or that require very careful management, or both. 54 Custom Soil Resource Report Class 5 soils are subject to little or no erosion but have other limitations, impractical to remove, that restrict their use mainly to pasture, rangeland, forestland, or wildlife habitat. - Class 6 soils have severe limitations that make them generally unsuitable for cultivation and that restrict their use mainly to pasture, rangeland, forestland, or wildlife habitat. Class 7 soils have very severe limitations that make them unsuitable for cultivation and that restrict their use mainly to grazing, forestland, or wildlife habitat. Class 8 soils and miscellaneous areas have limitations that preclude commercial plant production and that restrict their use to recreational purposes, wildlife habitat, watershed, or esthetic purposes. Capability subclasses are soil groups within one class. They are designated by adding a small letter, e, w, s, or c, to the class numeral, for example, 2e. The letter e shows that the main hazard is the risk of erosion unless close -growing plant cover is maintained; w shows that water in or on the soil interferes with plant growth or cultivation (in some soils the wetness can be partly corrected by artificial drainage); s shows that the soil is limited mainly because it is shallow, droughty, or stony; and c, used in only some parts of the United States, shows that the chief limitation is climate that is very cold or very dry. In class 1 there are no subclasses because the soils of this class have few limitations. Class 5 contains only the subclasses indicated by w, s, or c because the soils in class 5 are subject to little or no erosion.

Fragments This table shows estimates of particle size distribution and coarse fragment content of each soil in the survey area. The estimates are based on field observations and on test data for these and similar soils. Depth to the upper and lower boundaries of each layer is indicated. Particle size is the effective diameter of a soil particle as measured by sedimentation, sieving, or micrometric methods. Particle sizes are expressed as classes with specific effective diameter class limits. The broad classes are sand, silt, and clay, ranging from the larger to the smaller. Sand as a soil separate consists of mineral soil particles that are 0.05 millimeter to 2 millimeters in diameter. In this table, the estimated sand content of each soil layer is given as a percentage, by weight, of the soil material that is less than 2 millimeters in diameter. Silt as a soil separate consists of mineral soil particles that are 0.002 to 0.05 millimeter in diameter. In this table, the estimated silt content of each soil layer is given as a percentage, by weight, of the soil material that is less than 2 millimeters in diameter. Clay as a soil separate consists of mineral soil particles that are less than 0.002 millimeter in diameter. In this table, the estimated clay content of each soil layer is given as a percentage, by weight, of the soil material that is less than 2 millimeters in diameter. The content of sand, silt, and clay affects the physical behavior of a soil. Particle size is important for engineering and agronomic interpretations, for determination of soil hydrologic qualities, and for soil classification. The amount and kind of clay affect the fertility and physical condition of the soil and the ability of the soil to adsorb cations and to retain moisture. They influence shrink - swell potential, saturated hydraulic conductivity (Ksat), plasticity, the ease of soil dispersion, and other soil properties. The amount and kind of clay in a soil also affect tillage and earthmoving operations. Total fragments is the content of fragments of rock and other materials larger than 2 millimeters in diameter on volumetric basis of the whole soil. Fragments 2-74 mm refers to the content of coarse fragments in the 2 to 74 millimeter size fraction. Fragments 75-249 mm refers to the content of coarse fragments in teh 75 to 249 millimeter size fraction. Fragments 250-599 mm refers to the content of coarse fragments in the 250 to 599 millimeter size fraction. Fragments >=600 mm refers to the content of coarse fragments in the greater than or equal to 600 millimeter size fraction.

Adjacent to the permit area along the South Platte River bottom, there are trees, brush and grasses where livestock have been grazed. A minimum 250 foot wide band adjacent to this area will not be mined as it will be a buffer between the upper bank of the river and the developed reservoirs. The overall property appears to have had a long history of agricultural use as irrigated cropland. The attached tables are from the USDA soil survey report and show the typical vegetation types for different soils found within and adjacent to the mine. Uncultivated Lands 1. Current cover percent is: 20 to 65% 2. Topsoil depth on site averages: 5 to 12 inches 3. Seeding dates recommended: October 15 to May 1. 4. Fertilizer, if needed: Phosphate 5 40 lb/ac and nitrogen 5 40 lb/ac. 5. Seed mix to be used the grassed areas: Non -Irrigated grass seed recommendation Species Lbs.

Everist, Inc. mining sites in Weld County, and was originally prepared by the Platte Valley NRCS office. The seed will be drilled where possible and doubled if broadcast. The non -cropland areas have no special or unique characteristics, and consist mostly of a weedy -grass covering. The U.S. Army Corps of Engineers (File # NWO-2020-01166-DEN) has determined there are no wetlands on the permit area. In addition, there is no habitat on the permit area for Ute ladies -tresses orchids. Vegetation Information The following vegetation types were observed and mapped on the site. Irrigated cropland - covers about 77.0% ( .364 acres) of the mine. Historically, these areas have been used as irrigated fields in L.G. EVERIST, INC. - WEST FARM RESERVOIRS 75 November 2022 EXHIBIT J VEGETATION INFORMATION (cont) which corn, sorghum, grass hay or other cash crops have been grown. The farmer who leases the land will continue to cultivate these areas that are not being mined throughout the life of the mine. The farmer will determine what crops will be grown year to year and they will be responsible for planting and caring for the crops grown. Non -Irrigated Grass land and/or Vacant Land - covers approximately 10.1% (.47 acres). Most of the acreage covers the area between the terrace deposit of gravel and the floodplain on the west side of the river and is used as rangeland. Some wet soils are associated with the irrigation return flow ditch on the western parcels. The vegetation consists of mostly grass, weeds, and some cactus. The plant community is 80 to 85 percent grasses and 5 to 15 percent cactus and weeds. Grass species makeup 85% to 90%, by weight, of the non -cropland vegetation found on the site. OpenRangePasture - covers about 6.9% (.32 acres) . Historically, these areas have been used as open livestock grazing area along the South Platte River. The vegetation present in this area is mostly grass intermixed with weeds, scattered trees and brush. There are also areas were no vegetation exists as the underlaying gravel has been exposed due to past flooding. The plant community is 50 to 70 percent grasses and 30 to 50 percent, trees, cactus and weeds. Grass species makeup 40% to 45%, by weight, of the non -cropland vegetation found on the site. FieldBuffer - these areas cover approximately 2.6% (.12 acres) and cover the area between he irrigation return flow ditch and the terrace deposit or along the old railroad bed that. The plant community and covers are consistent with the Non Irrigated grass land areas. Most of this area will not be mined. Farming Facilities - these areas cover approximately 2.0% (,-.9 acres) . They contain houses, barns, sheds, livestock pens, corrals, irrigation pumping areas and equipment parking/storage areas. Vegetation on these areas is usually very sparse and consists of weedy patches and grass. Oil & Gas operations areas - cover approximately 0.4% ( .2 acres) . These areas will not be disturbed by mining and have little or no vegetation of any value. It is mostly weeds with some sparse L.G. EVERIST, INC. - WEST FARM RESERVOIRS 76 November 2022 EXHIBIT J VEGETATION INFORMATION (cont) grass areas surrounding the roads and bare ground. If the O&G areas remain after mining they will not be resoiled or seeded but graded for use by the oil companies. As mining progresses these facilities may be abandoned and if removed they may be mined. Transportation Corridors. - This is City and County ROW along WCR' s 32.5, and 21. These areas are not in the permit and will not be disturbed by mining so are excluded from the permit. Water areas - these areas are within the banks of the irrigation return flow ditch that crosses the permit. The water surface areas at this time cover approximately 1.10 (z5.4 Acres). The irrigation return ditch may be removed if it dries up and is not be needed once the reservoirs are constructed. L.G.

In this analysis L.G. Everist, Inc. will have approximately 56 acres disturbed in some form or another. The activities planned in this Operations Stage will include stripping, soil and overburden storage, sloping to the plant working floor, processing plant construction in Phase 4 and construction of the 6.0 acres ± recycled water facility in Phase 1. If development ended here the reclamation required would be to remove an estimated 200 yds of concrete foundations at processing plant, resoil the 50 acres and revegetate the disturbed area in Phase 4. In Phase 1 the settling ponds would have to be backfilled, resoiled and revegetated. We estimate 20,000 cyds would be needed to backfill the ponds. Adequate soil and overburden will be stored around the water recycling facility in Phase 1 for use on this area. The slurry wall in Phase 4 is not bonded as it is not installed in either Phase since mining will not start during Operations Stage A. From the TABLEL calculations we request the financial warranty amount for this scenario be set at $198,500.00 Doing this initial bonding will require LGE to file a Technical Revision to increase the bond before starting mining. Table L shows the estimated cost for this phase. Tables L-1, L-2, L-3 and L-4 show the estimated cost to reclaim each of the mining phases based on to days costs and are included for future reference. The Equipment Used in the Estimate Is: Scraper teams - 2 -Cat 627G scraper, D9R Dozer, 140H grader & water truck - Resoiling & backfilling Grader - Cat 140H - seedbed prep and ripping plant site Loader — Cat 688 — armoring placement Dozers - 2 - Cat D9R - cut/fill working face sloping Seeding team - standard farm tractor and pull behind drill, and crimping disk attachment L.G.

Please acknowledge receipt of the copy of the permit application by signing in the appropriate space provided below and returning one copy of this letter to the person delivering the book. This will be submitted to the Division of Reclamation, Mining & Safety to prove the application book was delivered to your office. Yours truly, ENVIRONMENT, INC. Stevan L. O'Brian enclosure RECEIVED THIS DAY OF , one copy of an application packet for above referenced mine. Weld County Clerk to the Board By L.G. EVERIST, INC. - WEST FARM RESERVOIRS 97 November 2022 EXHIBIT S PERMANENT AND MAN-MADE STRUCTURES (10/11/2022) Owner(s) of Record of a Structure(s) within 200 feet of the mine, will receive a letter and Structure Agreement as required by the Colorado Division of Reclamation, Mining and Safety (DRMS). As per the DRMS rules, when a permit application is filed, the rules require either: a. The operator/applicant requests a Structure Agreement with owners of any permanent man-made structures within 200 feet of the permit area. In the agreement, the operator agrees to reimburse the structure owner for any damage done to their structure as a result of the mining operation. OR b. The operator/applicant can provide the DRMS with a Geotechnical Stability analysis which demonstrates that any structures within 200 feet of the permit area shall not be damaged by mining or reclamation activities occurring at the above -referenced site. We are sending letters and Structure Agreements to the Owners of Record for the structures listed in this exhibit and expect to have some completed in the next 30 to 60 days. Copies of the completed agreements will be provided to Division when they are received. In lieu of receiving agreements from Structure Owners, L.G. Everist is including a Geotechnical Stability analysis in this permit application that has been prepared by Deere & Ault. It shows that the required safety factors are greater than State requirements at the slurry wall boundary, so the safety factors for any structure outside the boundary will be well above the state's requirements.

Applicable Regulation - Colorado Construction Materials Rule 3.1.10(6) states, "Methods of weed control shall be employed for all prohibited noxious weed species, and whenever invasion of a reclaimed area by other weed species seriously threatens the continued development of the desired vegetation. Weed control methods shall also be used whenever the inhabitation of the reclaimed area by weeds threaten further spread of serious weed pests to nearby areas." Noxious Weed Species The Colorado Department of Agriculture (CDA) has evaluated the noxious weed situation throughout the state and created weed management laws that apply state-wide. In 2004, the CDA updated weed management laws to create the A, B and C species lists. See current list on CDA's website at: https://www.colorado.gov/pacific/agconservation/noxious-weed-species (updated March -2017). List A Species are designated by the CDA for eradication. List B Species - CDA and local government develops and implements state noxious weed management plans designed to stop the continued spread of these species. List C Species are species for which CDA has left it up to the local governments to address if they choose to. The List C species are wide spread throughout the State of Colorado. Noxious Weeds commonly found on mine sites and agricultural lands in Weld County List B Canada Thistle Dalmatian toadflax Leafy spurge Russian Olive (tree) Salt Cedar/Tamarisk (bush/tree) List C Downy Brome/Cheat Grass Field bindweed Weed Control/Management during Mining and Reclamation The operator shall monitor affected and reclaimed lands for noxious weed infestations. If weed infestation occurs on the permitted land, the operator will perform a combination of the following practical operating practices and weed control methods during the life of the mine, until fully reclaimed/released. Minimize disturbed areas, disturbing only the acreage to be mined in the upcoming field season, and limiting the roads and equipment storage areas Reclaim affected areas as soon as possible - topsoil and vegetate with a native grass mix Minimize or eliminate wetted soils, create positive drainage at all times Vegetate topsoil and overburden stockpiles, and other disturbed areas, with a native grass mix to control erosion and weed growth Inspections will be will be conducted in early Spring and Fall to determine if weed spraying is needed before the native plants become active. Weeds will be sprayed with most effective chemicals for the species (using county and contractor recommendations - see Weld County specific recommendations below) Throughout the growing season, weeds will be mechanically controlled by various methods (mowing, pulling, dozing, chop -down, and other removal) Estimated Cost of Weed Control $5,000 - $10,000 per year 112 9-W F -DBMS -W eedPlan-Final.docx November 2, 2022 L.G. Everist, Inc. - West Farm Reservoirs site WEED CONTROL PLAN Weld County Weed Management - Techniques and timing for Weed Species Listed below (from Weed Division of Weld County Public Works) Downy Brome/Cheatgrass Esplanade at 5 oz/acre in July/early August as a pre -emergent treatment. Treatments will be made using both broadcast spray on the large patches and handgun treatments of the small patches. Esplanade has shown to provide two years' worth of control of cheatgrass whose seed longevity is fairly short. During these two years of cheatgrass suppression, the surrounding vegetation on the sites in the research plots has filled in to out compete the cheatgrass. With as much other vegetation that is in the area, it is believed that this will be the similar case at West Farm Reservoirs. A spring inspection in February/March (as soon as snow load is gone and the site is accessible) will be conducted to determine if any other treatments are needed before the native plants become active. Field bindweed, Canada thistle and Dalmatian toadflax Tordon at 32 oz/acre with an MSO surfactant at 32 oz/100 gallons will be used to treat these species in September/October of 2016. These patches will be treated by handgun work to limit any impact to surrounding forbs. A spring inspection in May/June will be conducted to see if a spring treatment is necessary or another fall treatment. 113 9-W F-DRMS-W eedPlan-Final.docx November 2, 2022 L.G. Everist, Inc West Farm Reservoirs BANK ARMORING PLAN This bank protection plan is presented to explain the bank armoring proposed for reservoir bank protection in Phase 2 that run parallel to the South Platte River channel. Only the reservoir side armoring is being proposed since the river bank lies 250 feet or more east of the top of the slope of the mining limits. No armoring is proposed in Phase 1 since the mining area is east of an old railroad embankment that isolates the reservoir from the river corridor. The location of the proposed armoring is shown on MAP EXHIBIT F - RECLAMATION PLAN MAP . The attached FIGURE1shows the cross-section of the area discussed below and details of the armoring to protect the banks along the north and east side of Phase 2. The RECLAMATION PLAN MAP shows the location of the area to be armored in the mine. The armor is intended to protect the reservoir banks should a 100 -year flood event occur after an area has been reclaimed. The armoring will be covered with a 10-12 inch layer of growth medium and seeded with the approved seed mix. The toe of the slope armoring will be at least 5 feet below the thalweg of the adjacent riverbed. The base of the armoring will average 10 feet below the existing ground surface at the mine. The 100 -year Floodplain line information has been included on all of the MAP EXHIBITS in the application Packet. Armoring material will be recycled concrete fragments with surface rebar removed, so that it meets the definition of Inert Materials. The concrete will be sized 9 to 15 inches averaging 12 inches. Fines will be mixed in to fill voids. This size material will have a Safety Factor of 1.26. See Bank Armoring Calculation page following this text. The operator will keep enough material stored on the mine to complete armoring needed on any area where sloping is being completed and is ready for armoring. At a minimum, 2,350 cubic yards will be stockpiled on the mine for use in armoring. This is enough to armor a minimum of 1,000 feet of excavation bank. At no time will there be more than 1,000 feet of armoring needing to be placed. The stockpile of armoring material will be placed parallel to the water flow so it will not interfere with flows in the flood plain if flooding occurs. It will be within the setback between the permit boundary and the mine highwall so it is close to the area where it will be placed on the bank. LGE - WEST FARMS RESERVOIR November 2, 2022 114 Waci Farm Racarvoirc Rank Armoring Plan (root) Reservoir Bank Armoring. Armoring will be placed inside of the mined areas adjacent to the South Platte River channel in Phase 2 only. In Phase 1 the top of bank into the reservoir will be no closer then approximately 347' and is protected from direct flooding flow by the old railroad embankment. The small section in Phase 3 is above the Flood Plain so will not be impacted by flooding. The armoring will be placed on the slopes starting from the existing ground surface elevation. The toe of the armoring will be a minimum of 5 feet below the river thalweg, have a 3h to lv slope and will be 2 feet or more thick. This will require approximately 2.35 cyd/lft along the excavated bank slopes. Once sloping begins, the armoring will be installed on 1,000 foot sections until completed. This will leave an armored face along the top of the bank and the slope into the reservoir that is 35 feet wide.

Everist, Mountain Division SUBJECT: West Farm Slope Stability ADDRESS: 7321 E. 88th Ave., Suite 200, PROJECT L.G. Everist West Farm Henderson, CO 80640 NAME/NO.: 20C26026.02 FROM: Susan Rainey, P.E., CC: This memorandum summarizes our analysis of proposed future mine slopes at the West Farm site, summarizes the subsurface conditions at the site, and presents our conclusions and recommendations regarding appropriate slope configurations to meet Colorado Division of Reclamation, Mining and Safety (DRMS) criteria. SLOPE STABILITY ANALYSIS Slope stability analyses of proposed future mine slopes at the West Farm site were performed using Slope/W, a limit equilibrium computer model software program. Maximum and average cross -sections were developed from the existing conditions (as determined from the 2019 ALTA survey performed by King Surveyors, and 2013 FEMA LiDAR) and based on conversations with L.G. Everist about potential future mining configurations at the site. The mine plan consists of two main mining areas (North and South) divided by Weld County Road (WCR) 32.5, as shown on Figure 1. In each area there are two mine cells planned: one on the lower portion of the property (to the east), and a second along the upper terrace on the western portion of the site. Slurry walls will be constructed around the perimeter of each of the four planned cells. A standard offset of 200 feet from the river, and 15 feet from property lines, right-of-ways or utilities was used for the proposed slurry wall alignment. An additional offset of 25 feet from slurry wall to top of mine highwall was used in our analyses. Two sets of analyses were performed: one for 3:1 (horizontal to vertical) free -draining native sand and gravel slopes, and one for compacted clay fill slopes with varying horizontal to vertical slopes. Each set of analyses included models at five different locations throughout the West Farm site, as detailed below. Each slope configuration was analyzed for full reservoir conditions, seismic loading and rapid drawdown. GEOTECHNICAL INVESTIGATION The general subsurface lithology at the West Farm site consists of one to four feet of overburden at the surface, underlain by alluvium sand and gravel deposits, followed by weathered Laramie Formation bedrock measuring about 2 feet thick, and finally less weathered Laramie Formation bedrock. The total depth to bedrock is estimated to varies from about 27 to 75 feet thick. Subsurface lithology data was obtained from two separate geotechnical investigations. The first investigation on the property, consisting of 31 borings, was performed by L.G. Everist in October of 2018. A second investigation, consisting of four borings, was conducted by Deere & Ault in January of 2022. The intent of the Deere & Ault subsurface investigation was to collect bedrock samples to confirm site -specific material strength properties. Two of the test holes were cored approximately 10 feet into bedrock, while brass sleeves were used to collect relatively undisturbed bedrock samples in the remaining two holes. Laboratory testing was performed on the samples collected by Deere & Ault in 2022 and focused on bedrock strength but also included gradations of the L.G. Everist West Farm Slope Stability aggregates. The 2018 investigation did not include any laboratory testing. The boring locations (for both 2018 and 2022) and summary logs for the 2022 borings are shown on Figure 1 and Figure 2. The locations of the slope stability cross -sections are also shown on Figure 1. ANALYTICAL PARAMETERS Material Properties As mentioned in the section above, bedrock samples were collected in January 2022 to confirm site -specific material strength properties at the West Farm site. Direct shear tests were performed on three bedrock samples. The direct shear on the sleeve sample, from boring B-4, returned an effective friction angle of 21.3° and a cohesion value of 1800 psf. The two core samples, from boring B-1 and B-3 were also tested and had effective friction angles of 55.8° and 29.8° respectively. The cohesion values for these two tests were 0 and 3400 psf. The bedrock sample from B-1 was logged as weathered. The cohesion value of zero for weathered bedrock correlates well with our experience of Laramie bedrock material properties. Summaries of the bedrock testing results are shown on the attached boring logs (Figure 2), and in the table below. The gradation test results for the alluvial showed expected results of sand and gravel with minimal fines (ranging from 2 to 10 percent). The laboratory testing results are included as Appendix A. Bedrock Strength Testing Summary Sample Effective Friction Angle 'P' (degrees) Effective Cohesion (Pct B-1 55.8 0 B-3 29.8 3400 8-4 21.3 1800 The selected unit weight, cohesion and friction angle parameters utilized in our slope stability analyses for West Farm are summarized in the table below. These values are based on decades of experience, published values for estimated Laramie bedrock strength parameters, and refined (reduced) strength parameters based on back calculations from a local displacement at a nearby pit. In our experience in the region, most failures are likely to occur through the bedrock. As you can see, the values we selected for our slope stability analyses for West Farm are more conservative than testing result values. Soil and Bedrock Parameters for Stability Analyses Unit Moist Unit Weight (Pct Effective Cohesion (pcf) Effective Friction Angle (p, (degrees) Overburden 125 150 28 Sand and Gravel 130 0 34 Slurry Wall 118 0 21 Fully Softened Laramie Bedrock 120 0 18 Fresh Laramie Bedrock 124 500 20 With these selected conservative bedrock parameters and site -specific material testing, in our engineering judgment it is appropriate to use the lower Factor of Safety requirements as outlined by DRMS in the current Policies of the Mined Land Reclamation Board (DRMS MLRB, 2018). We believe the slopes at West Farm qualify Project 20C26026.02 / May 16, 2022 Page 2 Deere & Ault, a Schnabel Engineering Company L.G. Everist West Farm Slope Stability as Critical Structures, due to their proximity to Weld Country Road 32.5 and utilities along the road. Accordingly, we have selected a recommended minimum Factor of Safety of 1.3 for static conditions and 1.15 for seismic conditions. Seismic Evaluation We used the 2014 USGS National Seismic Hazard Map to determine peak ground acceleration at the site to conduct seismic slope stability analyses. This map shows peak acceleration as a fraction of standard gravity as faint contours. We have obtained the contours from the USGS as a shape file. When the shape file is loaded into GIS a more detailed and interactive view of the contours is available. Based on this map we interpret West Farm to be located equal distance between the 8 and 10 contours (or 0.08 and 0.10 g), and therefore we have selected 0.09 g for the peak seismic ground acceleration. We used ground acceleration estimates for the 2 percent in 50 - year recurrence interval because it is the longest earthquake recurrence interval available, and thus represents the most conservative analysis. High Water Line A theoretical high-water line is shown for the full reservoir condition analyses. This high-water line is based on the current topographic map. The highest elevation closed contour was selected as the theoretical high-water line for each cell. ANALYTICAL RESULTS Slope stability analyses were performed for five conceptual models of the proposed slurry walls, representing conditions at the five section locations shown on Figure 1. As mentioned above, these models include the maximum section, which has critical structures, two average depth sections, and two sections best representing the upper and lower terrace. For each of the cross-section locations all analyses (full reservoir, seismic and rapid drawn down) were performed on 3:1 (horizontal to vertical) free -draining native sand and gravel slopes, and varying (3:1 and 4:1) compacted clay fill slopes. The top of mine highwall is in the same location for all slope conditions. For the clay fill slope configurations, an additional 12 feet of material is present at the crest, making the distance from slurry wall to top of slope 37 feet. In the five named cross -sections, slope height ranges from 35 feet to 63 feet. The compacted clay fill slopes for heights of 35 feet or greater are configured at 4:1 (horizontal to vertical). We have also analyzed a shorter slope height (25.5 feet). This shorter slope height analysis demonstrates that 3:1 (horizontal to vertical) compacted clay fill slopes will meet the required factors of safety. Dimensions and slope configurations are shown on the included Slope/W results. The slope stability analysis figures are provided in Figures 3 through 53. The following table summarizes the results for each section: Project 20C26026.02 / May 16, 2022 Page 3 Deere & Ault, a Schnabel Engineering Company L.G.

These required factors of safety are 1.3 for a full reservoir under static conditions and rapid draw down, and 1.15 for seismic conditions.

Activities within each Phase will include, but is not limited to, mining of sand and gravel, construction of reservoir liners, grading, resoiling and revegetation of the above -water perimeter areas of said reservoirs. 3. The Plant Site shown in the Phase 4 will be used throughout the life of the mine and activities may include, but are not limited to, processing the sand and gravel (crushing, washing and screening) ; crushing and recycling of concrete and asphalt materials: batching of ready -mixed concrete: batching of hot -mix asphalt; stockpiling of raw and finished products, and sales of said materials. 4. The Plant Site shall include the necessary processing plants and equipment to conduct the activities listed above, For the sand and gravel processing, and the concrete and asphalt recycling, the processing equipment shall include, but is not limited to, crushers, screens, conveyors, stackers, feeders, log -washers, and other necessary processing equipment. For ready -mixed concrete, and hot -mix asphalt, a concrete batch plant and an asphalt batch plant may be installed and used for the life of the mine. 5. The approximate locations of (2) Conveyor Crossing Envelopes are shown hereon. The exact location and size of the crossing areas will be determined prior to installation. A Technical Revision will be filed SkC,y{ny the overt Inratinn if riiffornnt frnrn chnw nn tfin A/lan Pvhihlt Mining Plan Map. These crossings will be used, when approved by the Town of Platteville, to build overhead conveyor facilities to transport raw material from the north side of County Road 32.5 to the processing plant. Using over -the -road conveyors would greatly reduce heavy off -road truck traffic that would cross the paved road. Conveyor facilities will be removed when reclamation is complete. 7. The reservoirs will have gravel access roads around the perimeters of each reservoir and the rest of the perimeter area will be revegetated with a state -approved seed mix. 8. Access points for each Phase are shown on this map. The accesses to the Phases will be used to move equipment, needed during mining and reclamation, from one area to the other. The access point into the Plant Site from County Road 21 will be used by customers' over -the -road trucks to transport finished materials to market. 9. Each Phase may continue to be used for agricultural purposes until the permitted mining operations begin in the area. 10.

The conveyor crossing envelopes shown on this map are the approved proposed crossings in the Town of Platteville PDP agreement. The conveyor design and final locations will be approved prior to construction of the conveyors. The approximate access points for each Phase are shown hereon. These accesses will be used to move equipment, and access each Phase during mining, development and maintenance of each Phase. 5. The unmined areas shown hereon may be used during mining and reclamation for placement of soil stockpiles, staging areas and as setbacks. If disturbed, they will be reseeded. 6. The settling and fresh water ponds shown in Phase 1 will be used for cleaning process water from the plant. Location may change to the reservoir floor once that area is mined. The FEMA Flood plain (Zone A) shown hereon is approximate and represents the best information available at the time this document was created and is subject to change.
